Method for generating ozone containing fluid
First Claim
1. A method of operating a hand cleaner dispenser to dispense ozone containing fluid onto a user'"'"'s hand comprising:
- providing a pump having an air compartment,operating the pump in a cycle of operation including the steps of drawing atmospheric air into the air compartment and discharging air from the air compartment,generating ozone within the air compartment from air in the air compartment by conversion within the air compartment of oxygen in the air within the air compartment into ozone to form ozonated air in the air compartment,mixing the ozonated air with a flowable fluid to form an ozonated fluid-air mixture, and passing the ozonated fluid-air mixture out a discharge outlet onto a user'"'"'s hand,wherein the pump comprises a housing and an impeller movable within the housing, the air compartment and the liquid compartment are formed within the housing between the housing and impeller,the air compartment is defined at least in part by a wall of the housing in which it transmits ultraviolet radiation,the method includes passing ultraviolet radiation through the wall into the air chamber to irradiate air in the compartment with radiation adequate to convert the oxygen in the air into ozone.

Abstract
A method of generating ozone containing fluid comprising: drawing atmospheric air into an air compartment, generating ozone within the air compartment from air in the air compartment by conversion within the compartment of oxygen in the air within the compartment into ozone to form ozonated air, discharging the ozonated air from the air compartment, mixing the ozonated discharged air with a flowable fluid to form an ozonated fluid-air mixture, and passing the ozonated fluid-air mixture out a discharge outlet. Preferrably the method is carried out in a dispenser utilizing a piston pump to draw air through a corona discharge ozone generator and to draw liquid from a liquid reservoir and simultaneously pass both the ozonated air and liquid through a foam generator to generate foam.
